Okay, so one common doctrine that Biblical repentence doesn't mean "Turning away from sin" but it means "Changing of ones mind" in greek. In other words, changing our minds about our Savior and accepting Jesus Christ.
As I'm lead to understand, what "repent" means is to "think beyond" or to "transform your understanding"; to think, beyond the carnal, worldly, earthly understanding of the law (which genders to bondage), and move to a higher understanding - the understanding of the mind of Christ, which is "in the heavenly places", and to begin to understand in the Spirit: as the apostle write concerning the "letter" as opposed to the "spirit": 2 Corinthians 3:6
In this manner we are set free from bondage to the "letter of the law" and serve in "newness of Spirit": that is, instead of "trying" and continually failing to fulfill the "letter of the law/commandments" we are to continually fulfill the Spirit of the law, which is "love your neighbor" and we produces the "fruits of the Spirit" instead of the "works of the law": Galatians 5:22-23: these bringing forth fruits "meet for repentance" and allow fulfillment of the "law of Christ" which was written through Spirit on the heart: Galatians 6:2: as opposed to the "law of Moses" which was graven by letter into stone: Romans 7:25, Romans 8:2, John 1:17, 2 Corinthians 3:3
Now, it is the "lawyers and Pharisees" which sit in the "seat of Moses": Matthew 23:2: they which "bind heavy burdens" accoring to the "letter of the law" and that of the "law of sin and death": Matthew 23:4: from which Christ was sent to "set at liberty": Isaiah 58:6, Luke 4:18, 2 Corinthians 3:17, James 2:12, 1 Peter 2:16
And we see these, trying again to bring people under the "yoke of bondage" to "obedience to the letter of the law": Galatians 2:4, Galatians 5:1, 2 Peter 2:19: and this "return to corruption" is return out of the "grace of God" which sets "at liberty" from sin, and to return to the "Egypt" of "bondage to corruption" or, "trying to live by the letter of the law" of which is said: Romans 10:5 and if you read the epistles, you'll find this theme at greater length, those "of the law" attempting to bring those "set at liberty" back into bondage to "works of the law", which is, "trying not to violate the letter of the commands" as a means of "attaining righteousness" which will never work: Romans 9:32, Romans 10:4, Galatians 2:16, Philippians 3:9
But, why in does Paul say in (Hebrews 10:26) that if we continue to sin willfully there remains no more sacrifice for sins?
Here the writer (not necessarily Paul) is speaking of this same theme, abandoning the "justification through faith" in an attempt to "return to bondage" and "work of your own will to works of the law in order to attain salvation":
Hebrews 10:1 Note the subject is "the law" and how it is not "the very image" but a "shadow of the very image"
Hebrews 10:2-3 Note that in this system of atonement, there is no "purged conscience" but a continual "remembrance of sins, every year"
Hebrews 10:9 Note "taking away the first, to establish the second"
Hebrews 10:22 Note that we are to have our very conscience "sprinkled" with the blood of one, perpetual atonement, covering all sin for all of time, that our conscience may be "purified by faith" and not "works of the law"
Hebrews 10:29 Note that; how are they "doing despite to the Spirit"? They are returning to "Egypt" or, "bondage to the law" in order to "attain righteousness"; and having done so, the have removed from the bounds of grace and faith, and fled back to Egypt to enter again into bondage in an attempt to be made "righteous"; now, in contrast to this, the writer begins the chapter of "faith" in chapter 11. This chapter speaks of faith in the "promise": Hebrews 11:2
Hebrews 11:13-15 Now, note these verse, and how these of faith sought a promise, and a place to come; and how they may have had "opportunity to have returned"; to return to that place from which they left: as we have in faith, "left Egypt" or "works of the law" in order to fully pursue "the promise" in "faith" and not by "works of the law":
So of this justification is written: Acts 13:39: Romans 3:21
Now, in these passages: Galatians 2:21, Galatians 5:4: is what is being meant by "drawing back to perdition" as written at Hebrews 10:38-39 and this "drawing back" is what the writer is speaking of as "no more sacrifice for sins"; that is to say, if one is brought again into the bondage of, righteousness through works by the following of the letter of the command, his conscience is not purged of sin, and he will bring into remembrance his sin, and his transgression, and his conscience will be burned, and his failure to attain righteousness through the letter of the command will cause fear and torment, and a continual "fearful looking for judgment" instead of a blessed hope in judgment by which we approach the throne of grace "boldly" knowing that our righteouness is not made perfect by the work of our own will, but by the finished work of Christ. Galatians 4:9 (note the word "elements" in this passage is the same as those 'elements' spoken of by Peter in his 2nd letter, which 'pass away' in 'fire'"), Colossians 2:6-8, ("rudiments" in this passage is also the same Greek as "elements" in the previous passages): Colossians 2:13-14
So what the writers are discussing at length is the tendancy of those who begin in faith toward the promise as an act of God, to "draw back" from that grace, and return to "bondage" to the "letter of the law" and the "written commandments" in an attempt to "perfect" their own salvation by their own will and work. If this is done, they have "frustrated the grace of God", and cause their own conscience, and that of others 'weak in the faith' to become "fearful" and looking for "fear and wrath" and begin to become fearful of God instead of finding the peace which sets at full liberty in love: 1 John 4:18
Also in (Galatians 5:16) Paul tells us to "Walk in the spirit and you will not fulfill the lusts of the flesh." He goes on in verses 19-21 to explain what lusts of the flesh are and says that people who fulfill the lusts of the flesh will not inherit the kingdom of God. One of them in specific is Adultery, a sin which Jesus said is either divorcing another or looking at another person lustfully. So, what exactly does Paul mean by these verses if we're not to try to turn away from our sins?
Note how the chapter opens: Galatians 5:1. Paul is again talking about removing from the Spirit and grace, back into the "yoke of bondage" the proverbial "Egypt" of the mind that "tries" to "obey the commandments". There is no "try" in regards to "righteousness by the letter of the commands"; there is only "failure", and with that failure, a "constant fear". Because, if you think that the sacrifice of Christ was not enough to make you every whit white and clean, and that you must "add" to the work of Christ, then there is no more "sacrifice" for the sin in your conscience. If the sacrifice of Christ is not enough in and of itself; then there is no further sacrifice to wholly remove sin from the conscience.
Galatians 5:5-6 Paul continues, nothing avails except faith working through love. But the people to whom he is writing are "trying" to add the works of the letter of the command to what they were first taught (their, first love) concerning the faith: Galatians 5:2-4.
Galatians 5:13-14. Now, we see here that Paul makes known that, althought we are set at liberty from "the ordinaces/commands" this liberty is not an an "occassion to the flesh" (that is, "let's sin and sin some more, all the time, all we desire") but that, unfeigned faith and unfeigned love, compells us to not want to do any harm to others, to, love one another. Thus, through the Spirit of unfeigned love, we do not "try" to "not murder": we simply are compelled to, not murder: we do not "forsake murder" because we attempt to "obey the law to attain righteousness" but we do not murder, because that is an act contrary to unfeigned love.
Romans 5:17 Now we see that there is a conflict between the two: flesh and Spirit, so that we
cannot do the things "that ye would": meaning, you cannot keep all of the law of commands; you
want to because of the Spirit, but you
cannot because of the flesh. So, all who would return to bondage will find that they
cannot do what the
want to; and this, through no fault of their own love, but because of the warring of the flesh against the Spirit.
Galatians 5:18
Galatians 5:19-21 Now here is the "works of the flesh", and these are what people who "try" to "work" and "obey the letter of the law" become: because they cannot keep the law, and by placing themselves under the law, they receive the curse of the law, and are found to be these things. Galatians 3:10, James 2:10, Romans 10:5. So if you try to "keep the letter of the rules" in order to "be righteous" then you have placed yourself under the "letter of the curse" which convicts you of being, all of these things "of the flesh"
But
Galatians 5:22-23
One who has completely left "bondage" and is moving forward fully in the Spirit, and hope of the promise through faith and love: these are they "against whom there is no law"; there is no accuser; for, only in the deeds of obedience to a set of rules can there be an "accuser" of whom then it was said to the Pharisees: John 5:45
